inactive
Disables a specified MEP.

mep <mep-id> interface port-
channel <port> direction
enable
Enables Connectivity Check (CC) to allow an MEP
sending Connectivity Check Messages (CCMs)
periodically to other MEPs.

no remote-mep <mep-id>
Deletes a specified destination MEP.

no mep <mep-id>
Deletes a specified MEP.
C

no mep <mep-id> inactive
Enables an MEP.
C

no mep <mep-id> cc-enable
Disallows an MEP sending Connectivity Check
Messages (CCMs) periodically to other MEPs.

ethernet cfm loopback remote-mep
<mep-id> mep <mep-id> ma <ma-index>
md <md-index> [size <0-1500>][count
<1-1024>]
Specifies the remote MEP ID, local MEP ID, MA index
and MD index to perform a loopback test.
This enables the MEP port (with the specified MEP ID) in
a specified CFM domain to send the LBMs (Loop Back
Messages) to a specified remote end point.
You can also define the packet size (from 0 to 1500
bytes) and how many times the Switch sends the LBMs.

ethernet cfm loopback mac <mac-
address> mep <mep-id> ma <ma-index>
md <md-index> [size <0-1500>][count
<1-1024>]
Specifies the destination MAC address, local MEP ID,
MA index and MD index to perform a loopback test.
This enables the MEP port (with the specified MEP ID) in
a specified CFM domain to send the LBMs (Loop Back
Messages) to a specified remote end point.
You can also define the packet size (from 0 to 1500
bytes) and how many times the Switch sends the LBMs.
E
13
ethernet cfm linktrace remote-mep
<mep-id> mep <mep-id> ma <ma-index>
md <md-index> [mip-ccmdb][[ttl
<ttl>]
Specifies the remote MEP ID, local MEP ID, MA index
and MD index to perform a link trace test.
This enables the MEP port (with the specified MEP ID) in
a specified CFM domain to send the LTMs (Link Trace
Messages) to a specified remote end point.
mip-ccmdb: Specifies the MIP CCM DB, a database
that stores information (tuples of {Port, VID, MAC
address}) about MEPs in the MD when receiving CCMs.
The MIP CCM DB is used for fault isolation, such as link
trace and loop back. An entry can remains in the MIP
CCM DB for at least 24 hours.
ttl: This is the time-to-live value (the number of
transmissions, 64 hops by default). Sets this to stop a
test once it exceeds the time duration without receiving
any response.
